CENTUM CS

With the actual implementations in many plants and absolutely high reliability, CENTUM CS has been the best seller of the large scale DCS since its first sale in 1993.

Since it was released in 1993, CENTUM CS is widely applied in the plants of oil refinery, petrochemical, chemistry, iron and steel, non-ferrous metal, metal, cement, paper pulp, food and pharmaceutical industries, and power, gas and water supply as well as many other public utilities.

The excellent operability and engineering technique, and the high reliability proved by the abundant actual application results, guaranteed that the CENTUM CS will continue to play an important role in the 21st century.

FCS

High reliable hardware that guarantee the plant control in stabilized status, the most important goal for plant control.

The FCS inherits the renowned reliability of the entire CENTUM series. Truly the most reliable FCS in the industry.

Since the processor cards perform control calculations, duplexes dual-redundant configuration of these cards is essential to prevent loss of control upon a hardware failure.In addition, two CPUs are paired in each processor card, thus the transient calculation errors can be detected. (This type of duplexes dual-redundant configuration is referred to as "Pair & Spare" configuration.)

In order to meet various requirements, in the FCS lineup, standard type, compact type and migration type FCSs are available for space saving installation, and high-distributed type FCS is also available for decentralized control structure.

Console Type ICS

Yokogawa provides three types of ICS to match your needs.

Console Type ICS
The Console type ICS is an operator console designed based on the human engineering with extensive capability and high reliability. It has one CRT or two stacked CRTs which support touch-panel function and eight-loop simultaneous manipulation.

Desktop ICS
A space-saving type of ICS with extensive capability and high reliability.

PICS
The ICS is a general-purpose personal computer with UNIX operating system. It also has space-saving advantage.

Dedicated Operator keyboard

Dedicated Operator keyboard

The dedicated operator keyboard for PHIS is assembled with the dustproof and drip-proof flat keys, and the keyboard maintains the same functionality as the operator keypad fixed atop the console type ICS
